Xii starts running when using android music app with bluetooth headphones

After listening to the Android Music player with my Bluetooth head phone I press pause on it to have the music stop playing. Now the android player stops playing, but Xiia seems to start playing. This happens even when Xiia does not appear to be running.
I use a sony dr-bt-21g headphone with a htc hero with android 2.1 update 1.
Anyway great app!
